Keystone robbers

An Australian judge on Monday described a pair of bumbling thieves, who stole a bag of bread rolls from a restaurant before one of them accidentally shot his accomplice, as "Keystone robbers."

Benjamin Jorgensen and Donna Hayes attempted to rob the Cuckoo Restaurant in Melbourne on April Fool's Day last year, but escaped with the wrong kind of dough when they mistook a bag of bread for the day's takings, the Victorian County Court heard.

But the mistakes did not end there -- Jorgensen, 38, then made for the wrong getaway car before accidentally shooting Hayes, 36, in the hip.

"I've heard of the Keystone Cops -- this is Keystone Robbers," Judge Roland Williams told the court.

Jorgensen and Hayes have pleaded guilty to armed robbery, the Australian Associated Press reported.

Jorgensen has also pleaded guilty to negligently causing serious injury over the sloppy shooting, which saw Hayes hospitalised for a month, it said.
